# The following example shows the db_tuple object class being
# allocated two permissions:
class db_tuple { relabelfrom relabelto }
# The following example shows the db_blob object class
# inheriting permissions from the database set of common
# permissions (as described in the "Associating Permissions
# to a Class" section):
class db_blob inherits database

# The following example (from the access_vector file) shows the
# db_blob object class inheriting permissions from the database
# set of common permissions and adding a further four permissions:
class db_blob inherits database { read write import export }
